Russian authorities have added several more U.S. products to a list of items that Moscow has banned since the West imposed sanctions over Russia's annexation of Crimea and its support for pro-Russian separatists in eastern Ukraine.

Russia's agricultural watchdog, Rosselkhoznadzor, said on August 4 that its services found aerobic mesophylls and facultative anaerobes in poultry shipped from U.S.-based Sanderson Farms, Inc. and Tyson Foods, Inc.

Also on August 4, Rosselkhoznadzor said it increased control over imports of veal from the U.S.-based Marcho Farms company, citing the detection of tetracycline in the meat.

Russia's consumer protection watchdog, Rospotrebnadzor, said on August 4 that it is preparing to suspend imports from the United States of "Kentucky Gentleman" bourbon.

The group said its experts found signs of organic chemicals in the bourbon that can cause health problems.
